To all whom it may concern: Be it known that I, AUGUST L. Lesson; a "citizen of-the United- S;tates,' residing at Qlevelandin the county of Cuyahoga and I ve inveinted certain new "and useful, Improvements in Concrete (Re; I inforcem'ent, of which the fellow ing is .a specification. ,M Q v My invention relatesto anevvand origii r' concrete'structnral' Work," all substantially fasbshotvn and de'-. :scribed and particularly pointed out in the 51 m r.

Thus, arepresents a rod or bar of sufiicient size in cross section to serve the purpose,

depending much upon the place of its use depth 'andiweight of the concrete 0 to he supported. These rods usually are angular in cross section and tw1sted length wise and are placed at suitableintervals apart and according to the length or the said ties are made out of Wire of a suitable'size and have somewhat peculiarly shaped ends to serve several important pur-- poses, chief of which are the engagement upon the said rodsin the loops 2 and sup hile the concrete is green as Well as tying the rods permanently together. To'th'ese ends the said Wires or ties have their ends bent reversely to form an open oop 2 at the immediate ends of the nto substantially stirrup shape, as at 3, 5 and 6. Thus,

the portion 3 constitutes a leg and the'portion 5 a straight rest or foot.and the end 6 an inclined portion extending back to the The end 6 is somewhat .sothat it will of the rod and prevent its gageme'nt from Within. the

It -will also be seenzthat the en-. trance to loop '2 is somewhat contracted, and requires the spring-ingbac'k of stemgfi of the hook and the Widening of said enas".seen in Fig. l'toget into the said loop.' w 4 Y The-openv loops 2 are formed beneath the body of the Wirein this instance While the upporting portions '3 entend below said loops and at right angles there- H to; and said hook portions also have theirfree stems 6, extending laterally to opposite sides of the body ofthe tie and in end View appear as seen; in Fig. 5. The real function of the so-calledl1ooks 3 is not tohook onto serve as supports or legs for the tie and the rods or bars a.
